Types of engineered septic systems:


The most common engineered septic systems are mound, recirculating sand filter, and aerobic. Keep reading to find out which of these options is best for you.


Mound System : A mound system is one of the most common septic systems and they are frequently used in areas with high water tables of shallow bedrocks. It uses an elevated mound of sand as the drain field, afterwards, the septic tank pumps the waste into the drain field in small amounts. From there, it´s filtered through the sand and distributed into the native topsoil.



Recirculating Sand Filter System : Sand filter septic systems are basically large PVC- lines or concrete boxes filled with sand. A pump pushes the waste through the top layer of sand, where the system treats and filters the wastewater. And finally, the system scatters the wastewater through the drain field.


Aerobic System : The oxygen inside the aerobic treatment unit speeds up the bacteria activity along with the waste to break down efficiently. Aerobic systems might also require pre and post treatments tanks to get rid of bacteria before it spreads into the drain field.


Engineered septic system vs conventional septic system


Usually, conventional septic systems will be used when the property and soil conditions are ideal for a regular septic tank and either gravel drain field to distribute water into the ground. However, things can’t always turn out the way we plan and that’s what engineered septic systems are for. An engineered septic system is the perfect solution to conditions that may not warrant a conventional system due to many different factors. The good news is that there are lot of options (like the ones mentioned above), and the advanced technology will provide you with efficient solutions. Although both options are great, at the end, it will all come down to the specific issues and design of the property you own.
